Answer:
{r|r>0}
Step-by-step explanation:
Pressure is the amount of force exerted on a surface per unit area, P=F/A.
The pressure, in atmospheres (atms), of a liquid on the circular base of a bucket is represented by the composite function PoA(r), where P(A) = 375 / A and A (r) = pi r²
We know that the domain is the set of input values.
Pressure,
At r = 0, it becomes not defined.
It means that r can be any value that is greater than 0. Hence, the correct option is (c). i.e. {r|r>0}

Answer:
x = 4 ±
Step-by-step explanation:
Given
x² - 8x + 10 = 0 ( subtract 10 from both sides )
x² - 8x = - 10
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = - 10 + 16
(x - 4)² = 6 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ± ← exact solutions
